LAM P-BURNER.

SPECIFICATION forming part of Letters Patent 1\ l"o. 662,584, datedNovember 27, 1900. A

Application filed September 24, 1900. Serial No. 30,897. (No model.)

To all, whom it may concern:

Be it known that I, FRANK THEODORE WIL- LIAMS, a citizenof the UnitedStates, residing at Meriden, New Haven county, Connecticut,

5 have invented certain new and useful Improvements in Lamp-Burners, ofwhich the following is a full, clear, and exact description.

My invention relates to oil-lamps of the cen- IO tral-draft type, andparticularly to the burner construction thereof.

The chief object of my invention is to prevent unsteadiness orflickering of the flame. This I accomplish by means which cause the gasand the air to be mixed uniformly and in the most effective proportionsand which when lighted produces a flame of a steady character and ofpractically uniform height entirely around the burner. Incidentally theconstruction is such that the wick cannot be raised to an unnecessary ordangerous height. In addition to the foregoing features the constructionis such that the user can quickly extinguish the flame.

In the drawings, Figure l is a vertical section of my improved burner,showing the parts in one position. Fig. 2 is a similar view showing theparts in another position.

A is an outer wick-tube.

B is an inner wick-tube.

O is a wick.

The wick O is movable between the wicktubes A and I5 and may be raisedor lowered by means of any well-known wick-lift. (Not 3 5 shown.)

D is a guard supported upon the top of the wick O and movable therewith.Projecting upwardly and inwardly from said guard D is an annular flangeE.

F shows perforations which are formed around the upper side of theflange E and just above the guard D for the purpose hereinafterdescribed. The flange E overstands the inner wick-tube, and the guard Dis of such a size as to approximately fill the space between thewick-tubes A and B, but yet is sufficiently free to prevent cramping orbinding.

G is a perforated spreader which performs the usual function. Thisspreader maybe provided with a rib G, which may rest upon the flange E,so that when the wick C is raised or lowered the guard D, flange E, andspreader G will move simultaneously.

H is a stationary rod projecting upwardly through the top of thespreader Grand carrying at its upper end a stop I, which by preferenceis adjustable by means of a screwthreaded connection. In Fig. 1 of thedrawings the wick is shown as elevated and in the position ready tolight. In this position it will be observed that the stop I by engagingwith the spreader checks any further upward movement. When the lamp islighted, the products of combustion rise from the outer and inner sideof the wick, the products from the inner side passing out through theperforations F, whereupon they mingle the products of combustion whichrise from the outer side of the wick. The spreader or that portionthereof which projects down into the wick tube is by preferenceconsiderably smaller than the inner wick-tube, so as to afford a spacethrough which air may flow to the gas-chamber or parts adjacent to theinner side of the wick O. This air-supply may be augmented byincreasingthe perforations in the spreader down to a point below the exposedportion of the wick.

In Fig. 2 the several parts of the burner are shown in the position inwhich the flame is extinguished, the wick being lowered so that theguard D will drop down into the spaces between the wick-tube,effectively cutting off the supply of air, and consequently preventingcombustion. Heretofore the extinguishingguards have not projected intothe wick-tube, but have merely rested upon the upper edge of the same.In this case, however, the guard is permitted to drop down into thespaces between the wick-tubes, thereby effectively extinguishing theflame.

What I claim isj 1. In a device of the character described, an innerandan outer wick-tube, a wick-space between said tubes, an annular movablewickguard adapted to rest upon said wick the'inner edge of said guardbeing turned upwardly to form a supporting-shoulder for a spreader,

a spreader supported upon said upturned portion of the guard,perforations in the upturned portions of said guard, and an air-passagebetween said spreader and the said wicktube.

2. In a device of the character described, an inner and an outerwick-tube, a wick-space between said tubes, an annular movable wickguardadapted to rest upon said wick the in ner edge of said guard beingturned upwardly and inwardly to form a supporting-shoulder for aspreader, a spreader supported upon said upturned portion of the guard,perforations in the upturned portions of said guard, and an air-passagebetween said spreader and the said wick-tube.

3. In a device of the character described, an inner and an outerwick-tube, a wick-space between said tubes, an annular movable wickguardadapted to project into the space between said Wick-tubes, the edge ofsaid guard being turned upwardly, and a perforated spreader concentricwith said wick-tubes and guard.

Signed at Meriden, Connecticut, this 18th day of September, 1900.
